Description

Technical Field

[0001] This utility model relates to the field of detection devices, specifically a liquid-sensitive sliding detection device for mobile phone screens. Background Technology

[0002] As smartphones evolve into "all-scenario portable devices," their usage environment is gradually moving beyond "dry indoor environments." Issues caused by liquid contact have become a core pain point for users. In humid environments, liquids such as water, sweat, and beverages on the screen surface can simulate human touch, causing capacitive screens to "jump" or "touch randomly," severely impacting the user experience. As a result, many manufacturers have begun to add liquid-sensitive detection functions to mobile phone screens to reduce the occurrence of "jump" and "touch randomly" phenomena.

[0003] However, to verify whether the liquid detection function installed in a mobile phone is working properly, most existing testing technologies involve manually spraying liquid onto the phone screen and then judging whether the liquid detection function is working properly through the operation of the testing personnel. This is labor-intensive, and most visual inspection devices cannot meet the requirements for multi-liquid liquid detection. Therefore, a specialized testing device is needed to evaluate the performance of this function, which can simulate various liquid contact situations in actual use scenarios, thereby comprehensively and accurately reflecting the key indicators such as the response speed, sensitivity, and false alarm rate of the liquid detection function. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a mobile phone screen liquid-sensitive sliding detection device to solve the technical problem of mobile phone liquid-sensitive sliding detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone screen liquid-sensitive sliding detection device, comprising a mobile phone, a detection component, a stroke component for controlling the movement of the detection component, and a clamping component for clamping the mobile phone;

[0006] The detection assembly includes a probe, a liquid storage tank, multiple nozzles, a camera, and a mounting platform. The probe is fixedly connected to the bottom of the mounting platform, the liquid storage tank is fixedly connected to the top of the mounting platform, and the inside of the liquid storage tank is divided into multiple liquid storage chambers. The nozzles are fixedly connected to the bottom of the mounting platform, and each liquid storage chamber is connected to a nozzle. The camera is fixedly connected to the bottom of the mounting platform.

[0007] The clamping assembly includes a clamping platform for placing a mobile phone, a clamping plate for clamping the mobile phone, a sponge pad for protecting the mobile phone, and a waterproof frame. The clamping plate is detachably connected to the clamping platform, the sponge pad is placed between the mobile phone and the clamping platform, the waterproof frame is sleeved on the outer frame of the mobile phone, and the clamping platform is fixedly connected to the conveyor belt.

[0008] By adopting the above technical solution, the liquid storage tank is divided into multiple storage chambers, each connected to a nozzle, which can store different types of detection liquids to meet diverse liquid-sensitive sliding detection needs. The probe and camera are fixed together at the bottom of the mounting platform, which can realize liquid-sensitive sliding detection of the screen through the probe and record the detection process in real time with the help of the camera. This allows staff to analyze the data by combining the video and the data detected by the probe. The sponge pad can effectively buffer the contact force between the mobile phone and the clamping platform, preventing the bottom of the mobile phone from being damaged by direct collision. The water-proof frame can prevent the detection liquid from seeping into the inside of the mobile phone from the edge of the screen, protecting the core components of the mobile phone from liquid corrosion, ensuring that the mobile phone remains in good condition after the test, and improving the protection of the mobile phone during the test process.

[0009] Furthermore, the travel assembly includes a conveyor belt, a crossbeam, a connecting plate, a mounting frame, a first motor, and a second motor. The crossbeam is fixedly connected above the conveyor belt, the connecting plate is slidably connected to the crossbeam, the mounting frame is slidably connected to the end of the connecting plate away from the crossbeam, the mounting platform is fixedly connected to the end of the mounting frame away from the connecting plate, the first motor is fixedly connected to the side wall of the crossbeam, and the second motor is fixedly connected to the top of the mounting frame.

[0010] By adopting the above technical solution, the travel component, through the cooperation of the conveyor belt, crossbeam, connecting plate and mounting frame, as well as the control of the first motor and the second motor, can drive the mounting platform to move flexibly in multiple directions, thereby allowing the probe to accurately cover every area of ​​the mobile phone screen, avoiding detection blind spots and ensuring comprehensive detection.

[0011] Furthermore, a first threaded rod is rotatably connected inside the crossbeam. The first threaded rod is parallel to the horizontal plane. The first motor controls the rotation of the first threaded rod. The connecting plate is threadedly connected to the first threaded rod. A first slider is fixedly connected to the end of the connecting plate facing the crossbeam. A first slide rail is fixedly connected to the end of the crossbeam facing the connecting plate. The first slider is slidably connected to the first slide rail.

[0012] By adopting the above technical solution, the first threaded rod is threadedly connected to the connecting plate and its rotation is controlled by the first motor, which can more accurately control the moving distance and speed of the connecting plate, ensuring that the detection position of the probe in the horizontal direction is more accurate.

[0013] Furthermore, a second slide rail is fixedly connected to the end of the mounting bracket facing the connecting plate, a second slider is fixedly connected to the end of the connecting plate facing the mounting bracket, and a second threaded rod is rotatably connected to the end of the mounting bracket facing the connecting plate. The second threaded rod is perpendicular to the horizontal plane, and the second motor controls the rotation of the second threaded rod.

[0014] By adopting the above technical solution, the mounting frame and the connecting plate are slidably connected by the second slide rail and the second slider, and the second threaded rod vertically set on the mounting frame is controlled to rotate by the second motor. This vertical adjustment structure can flexibly adjust the height of the mounting platform and the probe, and can accurately control the contact between the probe and the screen according to the different thicknesses of mobile phone screens or different detection requirements, so as to prevent screen damage.

[0015] Furthermore, the clamping plate is inserted into the clamping platform.

[0016] By adopting the above technical solution, the plug-in connection method is simple and convenient to operate. When it is necessary to test mobile phones of different sizes or models, the staff only needs to pull out the original clamp and insert the clamp that is adapted to the size of the new mobile phone into the clamping table to complete the replacement.

[0017] Furthermore, the sponge pad is attached to the bottom of the phone, and the top of the sponge pad has a groove for placing the phone's rear camera.

[0018] By adopting the above technical solution, the sponge pad itself has soft properties and can form an effective buffer layer after it is attached to the bottom of the phone. When the phone is placed on the clamping platform, it can prevent the bottom of the phone from directly contacting the hard clamping platform surface, and prevent the bottom shell, camera, interface or button of the phone from being scratched or deformed due to collision or squeezing.

[0019] Furthermore, the sponge pad is attached to the bottom of the phone, and the top of the sponge pad has a groove for placing the phone's rear camera.

[0020] By adopting the above technical solution, a good buffer layer is provided for the mobile phone, ensuring that the mobile phone screen will not tilt due to the rear camera of the mobile phone, thus affecting the detection.

[0021] Furthermore, the inner wall of the waterproof frame is fitted to the outer frame of the mobile phone.

[0022] By adopting the above technical solution, the tightly fitted structure can form an effective protective barrier at the edge of the mobile phone screen. When the nozzle sprays the test liquid onto the screen, it can prevent the liquid from flowing from the gap between the screen and the outer frame of the mobile phone to the side or back of the phone, thus preventing the liquid from seeping into the circuit board, battery and other key components inside the phone.

[0023] Furthermore, the probe is a hemispherical probe, and a protective cover is detachably connected to the probe.

[0024] By adopting the above technical solution, the hemispherical probe surface is smooth and round. When it contacts and slides to detect the mobile phone screen, it can greatly reduce the frictional resistance between the probe and the screen. It can also simulate the operation of a human finger on the screen to a certain extent. When the probe is not in use, the protective cover can completely cover the probe surface to prevent dust, impurities and other contaminants from adhering to the probe surface and avoid impurities affecting the contact effect between the probe and the screen.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the setting of a probe, a liquid storage chamber, a nozzle and a camera, allows the probe to simulate the operation of a finger on the screen and record the voltage of the area, and the camera to observe whether the content of the mobile phone screen changes due to the sliding of the probe. The combination of the two can improve the detection efficiency and reliability. The liquid storage chamber can store different liquids, and the nozzle can spray liquid on the screen, which can be used to test the liquid sensitivity of the mobile phone screen under different liquids.

[0027] 2. This utility model, through the cooperation of the clamp, the waterproof frame and the sponge pad, not only prevents the mobile phone from shifting, but also protects the mobile phone to the maximum extent, preventing water damage and impacts. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In this example:

[0035] A liquid-sensitive sliding detection device for mobile phone screens, such as Figure 1-4 As shown, it includes a mobile phone 4, a detection component 1, a travel component 2 for controlling the movement of the detection component 1, and a clamping component 3 for clamping the mobile phone 4;

[0036] The detection component 1 includes a probe 11, a liquid storage tank 12, multiple nozzles 13, a camera 14, and a mounting platform 15. The probe 11 is fixedly connected to the bottom of the mounting platform 15, and a miniature capacitance sensor is provided on the top of the probe 11 to capture capacitance changes when the liquid comes into contact with it. The liquid storage tank 12 is fixedly connected to the top of the mounting platform 15, and the interior of the liquid storage tank 12 is divided into multiple liquid storage chambers 121 to meet the testing requirements of different liquids. The nozzles 13 are fixedly connected to the bottom of the mounting platform 15, and the nozzles 13 can evenly spray the liquid onto the screen of the mobile phone 4. Each liquid storage chamber 121 is connected to a nozzle 13, and each liquid storage chamber 121 corresponds to one nozzle 13 to prevent different liquids from contaminating each other. The camera 14 is fixedly connected to the bottom of the mounting platform 15, and the camera 14 is pointed at the screen of the mobile phone 4 to observe the changes that occur on the screen of the mobile phone 4 when the probe 11 is tested, so as to better analyze the liquid-sensitive reaction.

[0037] The clamping assembly 3 includes a clamping platform 31 for placing the mobile phone 4, a clamping plate 32 for clamping the mobile phone 4, a sponge pad 34 for protecting the mobile phone 4, and a water-proof frame 33. The clamping plate 32 is detachably connected to the clamping platform 31, which facilitates disassembly and quick replacement of the mobile phone 4 for testing. The sponge pad 34 is placed between the mobile phone 4 and the clamping platform 31 to prevent the mobile phone 4 from being damaged by rigid contact with the clamping platform 31. The water-proof frame 33 is fitted onto the outer frame of the mobile phone 4 to prevent liquid from entering the inside of the mobile phone 4 through the gaps in the outer frame and damaging the mobile phone 4. The clamping platform 31 is fixedly connected to the conveyor belt 21 to ensure that the screen area of ​​the mobile phone 4 can be tested completely.

[0038] See Figure 1 , Figure 4The travel assembly 2 includes a conveyor belt 21, a crossbeam 22, a connecting plate 28, a mounting frame 23, a first motor 26, and a second motor 27. The crossbeam 22 is fixedly connected above the conveyor belt 21 to ensure that the detection assembly 1 is above the mobile phone 4 for easy operation. The connecting plate 28 is slidably connected to the crossbeam 22 to facilitate horizontal displacement of the connecting plate 28 and improve mobility. The mounting frame 23 is slidably connected to the end of the connecting plate 28 away from the crossbeam 22 to provide a platform for subsequent component installation. The mounting platform 15 is fixedly connected to the end of the mounting frame 23 away from the connecting plate 28. The mounting platform 15 is fixedly connected to the mounting frame 23 by bolts to facilitate installation while ensuring that no displacement occurs that would cause the probe 11 to shift. The first motor 26 is fixedly connected to the side wall of the crossbeam 22, and the second motor 27 is fixedly connected to the top of the mounting frame 23.

[0039] See Figure 1 , Figure 4 A first threaded rod 29 is rotatably connected inside the crossbeam 22. The first threaded rod 29 is parallel to the horizontal plane to ensure that the connecting plate 28 can only move horizontally and prevent tilting. The first motor 26 controls the rotation of the first threaded rod 29, which can precisely control the rotation and direction of the first threaded rod 29. The connecting plate 28 and the first threaded rod 29 are threaded together. The rotation of the first threaded rod 29 controls the displacement of the connecting plate 28 on the crossbeam 22. A first slider 25 is fixedly connected to the end of the connecting plate 28 facing the crossbeam 22. A first slide rail 24 is fixedly connected to the end of the crossbeam 22 facing the connecting plate 28. The first slider 25 is slidably connected to the first slide rail 24. The cooperation of the first slider 25 and the first slide rail 24 provides a stable horizontal guide for the movement of the connecting plate 28, restricting the connecting plate 28 to move only in a fixed direction and preventing it from shifting left or right or swaying during movement.

[0040] See Figure 1 , Figure 4 The mounting bracket 23 is fixedly connected to a second slide rail 241 at one end facing the connecting plate 28, and a second slider 251 is fixedly connected to the other end of the connecting plate 28 facing the mounting bracket 23. This provides a stable vertical guide for the movement of the mounting bracket 23, restricting the mounting bracket 23 to move only in a fixed direction and preventing it from shifting left or right or swaying during movement. The mounting bracket 23 is rotatably connected to a second threaded rod 210 at one end facing the connecting plate 28. The second threaded rod 210 is set perpendicular to the horizontal plane, and the second motor 27 controls the rotation of the second threaded rod 210. This vertical adjustment structure can flexibly adjust the height of the mounting platform 15 and the probe 11.

[0041] See Figure 1 , Figure 2The clamping plate 32 is inserted into the clamping table 31. The plug-in connection method is simple and convenient to operate. When it is necessary to test mobile phones 4 of different sizes or models, the staff only needs to pull out the original clamping plate 32 and insert the clamping plate 32 that is adapted to the size of the new mobile phone 4 into the clamping table 31 to complete the replacement. There is no need to use screwdrivers or other tools for complicated disassembly and installation.

[0042] See Figure 2 The sponge pad 34 is attached to the bottom of the mobile phone 4. The sponge pad 34 itself has soft properties, providing a good cushioning layer for the mobile phone 4. The top of the sponge pad 34 has a groove for placing the rear camera 14 of the mobile phone 4, ensuring that the screen of the mobile phone 4 will not tilt due to the rear camera 14 of the mobile phone 4, thus affecting the detection.

[0043] See Figure 2 , Figure 3 The inner wall of the water-proof frame 33 is attached to the outer frame of the mobile phone 4. The tightly attached structure can form an effective protective barrier at the edge of the screen of the mobile phone 4. When the nozzle 13 sprays the detection liquid onto the screen, it can prevent the liquid from flowing from the gap between the screen and the outer frame of the mobile phone 4 to the side or back of the mobile phone 4, thus preventing the liquid from seeping into the circuit board, battery and other key components inside the mobile phone 4.

[0044] See Figure 3 The probe 11 is a hemispherical probe 11. The surface of the hemispherical probe 11 is round and smooth. When it contacts and slides to detect the screen of the mobile phone 4, it can greatly reduce the frictional resistance between the probe 11 and the screen, and can simulate the human finger to a certain extent. The probe 11 is detachably connected to a protective cover 5, which completely covers the surface of the probe 11 to prevent dust, impurities and other contaminants from adhering to the surface of the probe 11, and avoid impurities affecting the contact effect between the probe 11 and the screen, thereby interfering with the detection results.

[0045] The implementation principle of this embodiment is as follows: The mobile phone 4 is placed on the sponge pad 34 of the clamping platform 31, ensuring the bottom of the mobile phone 4 is in contact with the sponge pad 34. Then, a waterproof frame 33 is fitted onto the outer frame of the mobile phone 4, ensuring the inner wall of the waterproof frame 33 is in contact with the outer frame of the mobile phone 4. Finally, a clamping plate 32 adapted to the size of the mobile phone 4 is inserted into the clamping platform 31 to ensure stable clamping of the mobile phone 4. The first motor 26 is started to control the rotation of the horizontally arranged first threaded rod 29 inside the crossbeam 22. Because the connecting plate 28 is threadedly connected to the first threaded rod 29, and the connecting plate 28 slides on the first slide rail 24 of the crossbeam 22 via the first slider 25, the connecting plate 28 will drive the mounting bracket 23 to move horizontally until the probe 11 is initially aligned with the screen area of ​​the mobile phone 4. Then, the second motor 27 is started to control the vertically arranged second threaded rod on the mounting bracket 23. 210 rotates, and the mounting bracket 23 slides on the second slide rail 241 of the connecting plate 28 via the second slider 251, thereby driving the mounting platform 15 and the probe 11 to move in the vertical direction, precisely adjusting the contact distance between the probe 11 and the screen of the mobile phone 4, ensuring that the detection requirements are met and the screen is not damaged. Using the multiple liquid storage chambers 121 of the liquid storage tank 12 at the top of the mounting platform 15, the required type of detection liquid is sprayed onto the screen of the mobile phone 4 through the corresponding nozzles 13. Under the continuous control of the stroke component 2, the hemispherical probe 11 at the bottom of the mounting platform 15 slides smoothly along the screen to achieve liquid-sensitive sliding detection. At the same time, the camera 14 records the detection process in real time, completing the detection of the entire area of ​​the screen of the mobile phone 4. After the detection is completed, if the probe 11 is not used for the time being, its removable protective cover 5 can be covered to prevent the probe 11 from being damaged or contaminated with impurities.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
